This invention relates to new and useful improvements in surface tracks for railways and more particularly to a novel rail joint.

The principal object of the present invention 5 is to provide an interlapping rail joint of such construction and design as to preclude the possibility of one rail end sagging and the other rising at a joint as the wheels of rolling stock pass thereover, thus eliminating the rattling noise of rolling stock to an appreciable extent.

Other important objects and advantages of the invention will become apparent to the reader of the following specification.

In the drawings:

Figure 1 is a fragmentary perspective View of the joint.

Figure 2 is a top plan view of the joint.

Figure 3 represents a sectional view taken substantially on line 3-3 of Figure 2.

Figure 4 represents a perspective view of one end of the rail of this joint.

Figure 5 is a fragmentary perspective view showing the rail end complementary to the rail end shown in Figure 4.

Figure 6 represents an end elevational View of one of the rail ends.

Figure '7 represents a fragmentary bottom plan View of the rail joint.

Referring to the drawings wherein like numerals designate like parts, it can be seen that reference characters AB represent complementary rail ends making up the novel joint when they are secured together. It will be observed that each rail consists of the base portion 5, the upright web portion 6, and the ball or head portion 1. The ball portion of the rail is provided with an elongated extension 8 approximately one-half the width of the ball and this is tapered at its extremity as at 9 in an outward bevel. The base 5 is provided with a thickened extension [0 and at its inner end upstanding wall portions II merging with the ball 3, the wall on the opposite side of the rail end A (see Figure 4) merging with the underside of the extension 8 in the manner substantially shown in Figure 5 and denoted by numeral l2.

The ball I of the section A, and of course also of the section B as both rail ends are of the same construction, is beveled at the inner end of the extension 8 as at l3 and when these portions come together with the extensions 8 parallel in the manner substantially shown in Figures 1 and 2 they mesh with the beveled extremities 9 of the extensions 8 in which position the openings 54 of the rail end B and its extension 3 register with 5 the openings !5 of the extension 8 of the rail end A so that bolts Hi can be disposed therethrough. Each of the openings is countersunk at the outer side of the corresponding extension 8 to either receive the head I! of the bolt H5 or 0 the nut H! which is engaged on the bolt.

Obviously a joint constructed in this manner will eliminate the depression of one rail end while the other rises, which tends to cause a rattling noise as the car wheels pass over the step cre- 5 ated thereby, however slight.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size, and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the claimed as new is:

A rail joint comprising a pair of companion r rail section ends, each of said rails consisting of a a base, a vertical web and ball portion thereon, each of said rail ends being provided with a vertically transversely extending wall portion having its side edge inclined outwardly from the lower edge of the ball portion to the outer edge of the base to form a brace for the ball portion, each of said rail balls being provided with a reduced extension for interlapping relation when the rail ends are brought together and including a portion of the inclined wall portion, abutting base plates also including a portion of the inclined wall portion terminating short of the outer ends of the extensions for underlying and supporting the said outer end of the extension of an adjacent rail end, the vertical surface of the end of said extension and said wall portions being inclined laterally and abutting each other when the ends of the rails are united and bolts extending through the ball portions of said extension for 45 securing the same together, the ends of said bolts being recessed inwardly of the surfaces of the said ball portions.
